You want to research quicker and more effectively?               The Theoprax-Measuring System                makes this possible!  So far you have been able to record  - IR-Spectra  - NMR-Spectra  - UV-Spectra  - and so on,   now with the Theoprax-Automate you can record pH-Spectra  and study the interaction between different molecules  in dependence on the degree of dissociation of their  functional groups!    The new Theoprax-Method, based on conductivity measurements,  allows to characterize the interaction between molecules.     In complex chemistry, the pH-spectrum makes it possible  to make a statement about the concentration of the complex,  complexing agent and central ion. Furthermore, it shows  the preference of the complexing agent/central ion for  an metal ion/complexing agent in the presence of other  metal ions/complexing agents. The pH-spectrum also shows  the optimum pH-value for complex formation. It is no more  necessary to isolate it, you can do it in the solution.    In pharmaceutical chemistry and biochemistry the  pH-spectrum makes it possible to show the  enzyme-inhibitor-complex, enzyme-substrate-complex,  the catabolism of the substrate as well as the  pH-activity-curve of the enzyme. It is also possible to  show the interaction between antigen and antibody.    Are you interested?    Call Theoprax-Research!
